ABC/Lorenzo Bevelacqua(NEW YORK) — Ali Wentworth, veteran of In Living Color, and movies like Office Space, and immortalized as Jerry’s “Schmoopie” on Seinfeld, has a new comedy show called Nightcap, which debuts at 8 p.m. Wednesday night on the Pop network.

She plays Staci Cole, a frazzled guest booker for a fictional late night show, the host of which you never see, Wentworth explains to ABC Radio.

“It’s a very exaggerated look on all the dysfunctional people behind the scenes who get this show going every night,” Wentworth tells us, noting her experiences as a guest on The Tonight Show and other programs inspired Nightcap.

“To me, every time I was backstage…I would see, like, the pervy sound guy, and all the crazy people, and I kept thinking, ‘This is the show!’ … I saw so much crazy stuff, I said, this is a world that needs to be explored.”

As a guest booker, Wentworth’s character needs to book guests, so, “It’s all real celebrities playing themselves, so Gwyneth Paltrow, Sarah Jessica Parker, Michael J. Fox, they all come in and play a very funny version of themselves.”

One of those stars includes ABC News’ George Stephanopoulos, who happens to be Wentworth’s husband. On set, she jokingly called him a “diva,” and warned Nightcap staffers “not to make eye contact” with him.
